Abstract: Objective　To evaluate the value of TriAGe+ score in the diagnosis of stroke in patients with dizziness.Methods　A total of 1 437 patients with dizziness who received treatment from the Suzhou Hospital Affiliated to Anhui Medical University from February 2014 to August 2017 were enrolled.According to the final diagnosis，the patients were divided into two groups：stroke group （n=137，accounting for 9.5%） and non-stroke group （n=1 300）.The diagnostic value of TriAGe+ score for stroke in dizziness patients was determined by ROC curve and compared with ABCD2 score.According to the TriAGe+ score，those scored 10-17，8-9，5-7，0-4 were assigned to very high-risk group，high-risk group，medium-risk group and low-risk group，respectively.Comparisons were made between the 4 risk groups in terms of the incidence of stroke and between stroke and non-stroke groups in regard to clinical data.Stepwise Logistic regression analysis was performed for investigating the associated factors for stroke.Results　Patients with stroke and those without showed significant differences in the distribution of sex，blood pressure levels at admission，duration of dizziness，and type of dizziness，prevalence of functional limb weakness or speech impairment，prevalence of inducing factors for dizziness，prevalence of brainstem or cerebellar dysfunction，dizziness history percentages of labyrinth disorder or vestibular disease history，diabetes history，hypertension history，and atrial fibrillation history （P<0.05），except in the distribution of age （P>0.05）.Logistic regression analysis showed that sex，blood pressure levels at admission，functional limb weakness or speech impairment，duration of dizziness，inducing factors for dizziness，type of dizziness，brainstem or cerebellar dysfunction，dizziness history labyrinth disorder or vestibular disease history，diabetes history，hypertension history，atrial fibrillation history were associated factors for stroke in dizziness patients （P<0.05）.The incidence of stroke in very high-risk group，high-risk group，medium-risk group and low-risk group was 65.5% （57/87），27.0% （51/189），5.8% （23/394），0.8% （6/767），respectively，with significant differences （P<0.05），and the difference in terms of incidence of stroke between any two groups was significant（P<0.008 3）.For the diagnosis of stroke，the AUC of TriAGe+ score was larger than that of the ABCD2 score 0.890〔95%CI（0.866，0.914）〕vs 0.806〔95%CI（0.769，0.843）〕 （P<0.001）.When the TriAGe+ score was 10，its sensitivity was 0.834，specificity was 0.727，and Youden's index was 0.561.Conclusion　TriAGe+ score is contributive to quickly identifying stroke in dizziness patients.
